Contribution of features towards the predicted gestational age

The contribution of all the features in the random forest model towards the predicted gestational age at delivery as measured by the Shapley algorithm and reported as the SHAP value. This value is the average marginal contribution of a feature value across all permutations of features providing insight into the degree of influence of the feature on an individual's predicted gestational age at delivery. Each line represents a feature, and each dot represents a sample. The dot colour represents the value of the feature for the sample, with red being a high value and blue being a low value for that feature across all samples. SHAP=Shapley additive explanations.
